Sulphur Dioxide Gas Manufacturers

We are the manufacturer and supplier of SO2 gas cylinders with the following specifications:

We offer SO2 gas in cylinders of 5 kg, 10 kg, 50 kg, 100 kg, and 900 kg capacities.

Our cylinders are made from high-quality adhering to international safety and manufacturing standards.

The cylinders are designed for safe storage and transportation of Sulfur Dioxide gas at a working pressure of approximately 30 bar.

Cylinders are equipped with standard valves (such as CGA-660 or QF-11) and safety features like fusible plugs for overpressure protection.

Each cylinder is carefully tested with hydrostatic tests ensuring it holds up safely under pressure.

Our SO2 gas is offered with purity of 99.9% minimum, suitable for industrial applications including chemical synthesis, refrigeration, water treatment, and food processing.

We provide quality assurance certificates with each supply and ensure reliable delivery and technical support following industry best practices.
